SAMUEL I. ANTHONY, OF NEW YORK, N. Y.

FURNACE FOR GENERATING lLLUiVllNAT'lNC-GAS.

SPECIFICATION forming part of Letters Patent No. 311,403, dated January 27, 1885.

Application filed May 20, 1884. (No model.)

To @ZZ whom t may concern, 1

Beit known that I, SAMUEL I. ANTHONY, a citizen of the United States of America, and a resident of the city,county, and State of New York, have invented certain new and useful Improvements in Furnaces for Generating Illuminating-Gas, of which the following is a specilication.

This invention relates to a furnace and suital ble attachments for manufacturing illuminating-gas in one structure by the successive operations of decomposing steam in contact with incandescent or highly-heated carbon, car- 4bureting the resulting gaseswith the vapors of hydrocarbon oil,and combining and iixingthe carbureted gas in such manner as to retain in the generator the lampblack and other contaminating impurities usually passed off with #the gas; and the improved apparatus embraces a number of novel features of conf 'uction, the most important of which are, st, tile-guides projecting inwardly from the ,i lrnace-lining and inclosed nozzles for the in- A Avnhoduetion of steam and oil at different heights into the central ,portion of the 'body of fuel; lconch heating-channels for the steam-pipes in the wall of the generator and connecting with he fuel-chamber by heat-circulating passages; third, reversible perforated tile 3G strainers located above the fuel in the fixingchamber, serving as heaters for the gas and to remove impurities therefrormand other minor features, liereinaiter more fully described.

The objects of the invention are to introduce the steam and oil for generatinggas' away from the lining of the cupola into the inner portion of the body of heated fuel, and thereby secure better distributiouof the steam through such fuel, and consequentlyits more thorough decomposition, and also secure more complete mingling 0f oil vapor with the gases resulting from the decomposed steam; also, to provide the generator with means for rubbing and straining the generated gas,whereby it is subjected to frictional contact in finely-divided streams with numerous heated surfaces of refractory material, and thus effectual] y liXed, lwhile the lamp-black and tarry matter are retained within the generator and afterward 5o burned to aid in heating up the fixing-cham ber. I attain these objects by the improved and through its side passes the air-pipe O,

which is connected with the blower and has the air-valve D. The base E of the cupola, containing the ash-pit, has at its top an inward-projecting flange, F, and to it is pivoted the grate G of the cupola. Said grate is made of two opposite equal sections, each with iingers projecting into the spaces between the fingers ofthe other at its loose end, and each section has a lug connected with a crank, H, upon the horizontal rock-shaft I at the ash-pit bottom by means of a connecting-link, J. Said rock-shaft is held in proper bearings, and has one end passing through a stufiingbox in the side of the ash-pit, and its outside end is made square for the application of a lever or wrench for turning said shaft. Both sections of said grate are furnished alike with said rock-shaft I, and by that means each section of the grate is shaken and maybe dumped. The interior of the cupola above` the grate is made cone shape, its sides contracting at its upper portion and the top end terminating semi-spherically, as shown, and having thegas-outlet top opening, K.

A suitable distance above the grate G are located the steam-nipples L, by which the steam is introduced into the cupola. The distance from the grate to said nipples should be sufficient to always have remaining live coal close to the top of the grate afterthe generation of gas by decomposition of steam, in order that the fires may be quickly lighted during the period of blowing up the same.

A suitable distance below the top of the coal are located the oil-nozzles M, through which the oil is introduced into the cupola.

For both the oil and steam nozzles the cupola-lining is made with inwardly-projecting IOO tile-guides N, so that each nozzle is protected,

' and that it conducts the oil or steam into the heart or middle portion of the incandescent coal and away from the cupola-lining, so as to prevent them from passing along the lining and escape from being properly heated..

VBoth the oil and steam nozzles are placed inlining. The cupola at this place is-enlarged to have sufficient lining` and room for said pipe and chamber Bf, and said chamber is connected by the openings It with the interior of 'the cupola, to heat said pipe and superheat the steam therein. The exterior of the cupola is lined with iron, as shown.

S S represent the gas-strainers. With small cupolas one of them may be sufficient, while with -larger ones more than two of them may be employed. They are arranged in the xing-chamber of the cupola below the outlet of 'of said shell. ing secured on the inside of the shell.

the gas in a horizontal lateral direction. Each is constructed of metal and tile, disk shape,

and with central trunnion shaft ends, T. One end of said shaft passes through the lining and metal shell of the cupola, and passes through a stuffing-box secured-on the outside The other end is heldin a bear- The extreme outer end of said shaft is furnished with the ratchet-wrench lever U, for turning the strainer. In employing several strainers they are connected by cog wheels or cranks andl conneeting-links,' so that they are all operated together. rlhe disk portion of the strainer is composed of a disk-shaped tile, which is suitably perforated for the passage of the gas. The metal portion of the strainer is made in two semicircular frame-sections having slotted ends overlapping .each other. Between these frames the tile is received and held. From each section one of the trunnion shaft ends T extends opposite the other, and the tile has a groove on its periphery and a central lateral opening through it. In said groove the circular frame is tted,and through the central lateral opening is inserted a crossbar, V, which engages and locks the ends of the semicircular frames together and secures the tile between them. During the time of feedingthe cupola and blowing the fire up the strainers are placed in a vertical position, as shown'in Fig. 2. While the gas is generating said strainers are placed in horizontal position, as shown in Fig. 1.

'l Centrally overI the gasoutlet K is located the cupola top seal, W, on which the gas-outlet X is attached, and passes the gas down to the wash-box.

At the junction of the horizontal portion l `structed to seal by sand, and both for that purpose have an annular chamber, Z, in which the sand is contained.

a a represent the sealcaps, the rims of which pass into the sand when closed. For raising and lowering the caps a a, I employ the pinions b b, which engage the rack-bars c c, secured each, respectively, to its cap a. The pinion b of the seal W is mounted upon the horizontal shaftk d, which is guided in the bearing e, and has a hand-wheel, f, for operating the same. The bearing e is pivoted upon a vertical stud, g, attached to the top seal, W, so that after raising the seal-cap a out from the sand the bearing e is turned with the cap a off from over the opening in the top seal, W, for feeding and'blowing up the fire in the cupola, as shown in Fig. 2.

In the seal Y the pinion b is mounted on the shaft h, which is guided in the stuffing-box z', cast onthe outlet-pipe X, and said shaft has the hand-wheel j upon its outer end, by means of which the pinion is turned and the cap raised or forced into the sand.

What I claim as my invention, and desire to secure by Letters Patent, is-

l. In'combination with the fixing-chamber l of la gas-generator, the perforated tile strainer IOO provided with means whereby it may be p placed horizontally across the chamber or tilted at any desired angle, for the purpose described.

2. In combination Iwith a gasgenerating furnace, the perforated strainer provided with journals or shafts fitted in the walls of the furnace above the fuel-chamber, and means for operating such shafts, for the purpose described.

3. In combination with a gas-generating furnace, the perforated strainers composed of refractory material fitted within a metallic band, and provided with means for supporting it in the walls of the furnace and permitting it to oscillate as required, for the purpose set forth.

4. In combination with 'a gas-generating furnace', the tile-guides projecting from the walls into the feed-chamber a short distance above the grate, the steam-nozzles passing IIO through such guides, and connected steamsupply pipe, whereby steam to be decomposed is delivered into the central portion of the fuel. t l

5. In combination with a gas-generating furnace, the projecting tile-guides and steamnozzles, the heating chamber or channel formed in the wall of the furnace and connected with the fuel-chamber by suitable passages, and the steam-supply pipe placed insuch heatingchannel, as set forth.

' 6. The wall ofthe generating-furnace formed with a surrounding enlargement provided with a heating-chamber extending around the fuelchamber and connected therewith by pasi sages, in combination With the steamsuper- 9. In combination with a gas-generating cupola, the lower and upper tile-guides, provided, respectively, with steam and oil nozzles, and the perforated strainers located in the fixing-chamber of the cupola, for the purpose described.
